1/2 Inch Width = A Full Strip

I’m fixin’n to hang faux grasscloth on this accent / headboard wall in a master bedroom in the Spring Branch area of Houston. The textured wall has been skim-floated , sanded smooth , primed , and is ready for wallpaper .

The material is 20.75″ (20 and 3/4″) wide . So here I’m measuring off how many strips of wallpaper I’ll need.

I’ve counted out seven strips across the wall, and have come to my last (8th) strip. Look at my pencil mark – it’s at 21.” Remember that the paper is 20 3/4″ wide. This means that, to cover that last, scant 1/4″ width , I’ll have to use a ninth strip. Which will be a whole 9′ high strip that’s 20.75″ wide.
Useing a 1/4″ wide strip off a 9′ long length leaves us with a whole lot of waste – paper / square footage just going into the trash.
This is, again, why you should not purchase wallpaper based on square footage. It’s more a matter of determining how many strips you will need – factoring in the pattern repeat, etc.
Even better , have the wallpaper installer make a site – visit and calculate for you.
Going a step further … Since this is a (faux) grasscloth and has not pattern match , the seams will all be visible . So we try to balance the panels on the wall. Meaning, the wall will look better with panels of equal-widths, instead of, for instance, eight panels at 21″ wide and one at 1/2″.
For the record, it also looks better to not have a seam fall at dead-center on the wall. Better to have that center panel straddle the mid-point.
With this particular install, that’s what I chose to do. I took the first (let’s just call it 21″ wide for ease) … I took the first 21″ wide panel and used my laser level to line it up so 10 1/2″ fell on either side of the center line on the wall. So, this first panel was straddling the center line.
From there, I used full-width (21″) panels one either side.
Until I got to the last panel on the left, and the last one on the right. These two ended up each being about 15″ wide. So I had seven panels that were 21″ wide, and then two flanking on either side that were 15″ wide. This gave the wall a nice, balanced, uniform look.
Yes, I could have hand-trimmed each strip to 19″ wide or whatever the math would have worked out to. But my option was simpler, faster, maintained uniformity between the majority of the panels, as well as uniform width on the two outer panels, eliminated the worry of gaps at the seams due to unevenly trimmed rigid vinyl goods, and the 6″ width difference wasn’t very noticeable. And, also, since this was a faux grasscloth and color variations were minimized, you could hardly see the seams, nor the width of the panels, anyway.
From 5′ away, this wall looked perfectly homogeneous .
